Toolkit - Agno

The Toolkit class provides a way to group and manage multiple tools (functions) together. It handles tool registration, filtering, caching, and execution control.

Import

from agno.tools.toolkit import Toolkit

Constructor

Parameters

Parameter	Type	Description
`name`	`str`	A descriptive name for the toolkit.
`id`	`Optional[str]`	Reserved stable identifier for the toolkit. Defaults to `name` lower-cased with spaces and underscores replaced by hyphens (`"My Toolkit"` → `"my-toolkit"`), the same derivation Agent, Team, and Workflow use. Shown in `repr(toolkit)`; nothing else reads it in Agno v3.0 — AgentOS and the registry key toolkits by `name`.
`tools`	`Sequence[Union[Callable, Function]]`	List of callables or `Function` objects (from the `@tool` decorator) to include in the toolkit.
`async_tools`	`Sequence[tuple[Callable, str]]`	List of `(async_callable, tool_name)` tuples registering async variants whose names differ from the sync methods, e.g. `[(self.ascreenshot, "screenshot")]`.
`instructions`	`str`	Instructions for using the toolkit. Can be added to agent context.
`add_instructions`	`bool`	Whether to add toolkit instructions to the agent’s context.
`include_tools`	`list[str]`	List of tool names to include from the toolkit. If specified, only these tools will be registered.
`exclude_tools`	`list[str]`	List of tool names to exclude from the toolkit. These tools will not be registered.
`requires_confirmation_tools`	`list[str]`	List of tool names that require user confirmation before execution.
`external_execution_required_tools`	`list[str]`	List of tool names that will be executed outside of the agent loop.
`stop_after_tool_call_tools`	`List[str]`	List of tool names that should stop the agent after execution.
`show_result_tools`	`List[str]`	List of tool names whose results should be shown to the user.
`cache_results`	`bool`	Enable in-memory caching of function results.
`cache_ttl`	`int`	Time-to-live for cached results in seconds (default: 1 hour).
`cache_dir`	`str`	Directory to store cache files. Defaults to system temp directory.
`timeout`	`Optional[int]`	Timeout in seconds for the toolkit’s primary I/O operation (HTTP request, SDK call, sandbox execution). Subclasses forward their own `timeout` via `super().__init__(timeout=...)`.
`auto_register`	`bool`	Whether to automatically register all tools in the toolkit upon initialization.

In Agno v3.0, id is the second positional argument, after name. Positional tools no longer works: Toolkit("my_tools", [my_fn]) assigns the list to id and registers no tools, without an error. Pass tools by keyword — Toolkit(name="my_tools", tools=[my_fn]). Built-in toolkits are unaffected.

Usage Examples

Basic Toolkit

from agno.tools.toolkit import Toolkit

class WebSearchTools(Toolkit):
    def __init__(self, **kwargs):
        tools = [
            self.search_web,
        ]
        super().__init__(name="web_search_tools", tools=tools, **kwargs)

    def search_web(self, query: str) -> str:
        """Search the web for information."""
        return f"Searching for: {query}"

Toolkit with Instructions

class CalculatorTools(Toolkit):
    def __init__(self, **kwargs):
        tools = [
            self.add,
            self.subtract,
            self.multiply,
            self.divide,
        ]

        instructions = "Use these tools to perform calculations. Always validate inputs before execution."

        super().__init__(name="calculator_tools", tools=tools, instructions=instructions, **kwargs)
    
    def add(self, a: float, b: float) -> float:
        """Add two numbers and return the result."""
        return a + b
    
    def subtract(self, a: float, b: float) -> float:
        """Subtract two numbers and return the result."""
        return a - b
    
    def multiply(self, a: float, b: float) -> float:
        """Multiply two numbers and return the result."""
        return a * b
    
    def divide(self, a: float, b: float) -> float:
        """Divide two numbers and return the result."""
        return a / b
